how to burn .bin and .iso

[banzai16]

I have images in .bin and .iso format. I have the burn progs CDclone, Nero5 and Win on CD 5.
The only prog able to load a .iso image was Nero. All others just stalled. If I want to burn the image with Nero it tells me that "the block size does not correspond to the image length". I tried to ignore the message or to change the block size. Nothing I did created a working CD. What can I do. Why do the other progs not read .iso images?
Next problem with another .iso image. I received the error message "unexpected exception" and Nero cancelled the burn job. What does this mean?

So far I was not able to find a burn prog which was able to read .bin images. Who knows help.
Thanks
